Paying off a vacation is a great step in the right direction, Donovan. You must be getting excited about your upcoming trip!
The method for making that final payment will depend upon the type of reservation you have. If you purchased a vacation package, you will most likely be able to make that payment via the
My Disney Experience app. Make your way to the “My Plans, Reservations, and Tickets” section and you should see your hotel. Beneath your reservation dates, there should be an option to “Show Details.” That is the section where you'll want to look for the information to pay off your balance. If it's not there, you will need to
call and speak with a Cast Member to complete that payment.
If, on the other hand, you have a room only reservation, you will not be able to make final payment through the app and you will need to call to speak with a Cast Member.
I hope that helps, Donovan. Have a fantastic time!
